About Coastal Sensing

At Coastal Sensing & Survey we specialize in hydrographic and marine geospatial services and we deliver high‑resolution, decision‑ready data for complex coastal, offshore, and inland water environments. In 2005 we started diving and became enamored with the underwater world right in our back yard. Over the years, the marine survey industry has changed significantly. New sensors, platforms, and processing techniques have reshaped how data is collected and used. Coastal Sensing has grown alongside those changes, continually adapting our approach and investing in better ways to capture and interpret coastal data. Staying current has never been about chasing trends for us, it has been about doing the work well as the industry evolves.

We partner with clients who need confidence—engineers, developers, regulators, and asset owners—by turning challenging marine conditions into clear, actionable insight.

Our work supports the full lifecycle of marine projects, from early site characterization and permitting through construction, inspection, and long‑term asset management.

The Team: Here at Coastal Sensing we couldn’t do the fantastic work we do without a powerhouse group of individuals helping bring clarity and understanding to our subsea environment.
